6' Claims.

This invention relates to improvements in golf holes and more:particularly to an improved form of. golf practice hole such as usedindoors for practicing putting.

The main objects of the invention are to provide an inexpensive deviceof the character described which may be economically made and which maybe collapsed or folded into small compass for storage and shippingpurposes.

Other objects and advantages of the invention will be understood byreference to the following specification and accompanying drawingwherein there is illustrated a golf hole embodying a selected form ofthe invention.

In the drawing:

Fig. 1 is a plan of the blank sheet form from which the device is made.

Figs. 2 and 3 are plans showing successive steps in the manufacture ofthe device.

Fig. 4. is a section on the line 4-4 of Fig. 3, and v Figs. 5 and 6 area perspective and side elevation, respectively, of the completed device.in condition for the use for which it isv intended.

Referring now to the drawing, the improved golf practice hole is formedfrom suitable sheet material, preferably a suitably heavy grade ofcardboard, the same being blanked out to approximately hexagonal shapeas indicated in Fig. 1. The blank designated I0 in its entirety, isprovided with score lines ll, l2, l3, I4, l5 and I6, which radiate froma central opening I! and extend to the corners of the hexagonal sheet.

The wall section formed between the score lines II and I6 is split asindicated at 18, and it will be observed that in the flat blank formillustrated in Fig. 1, the opposed score or fold lines are not quite inlongitudinal alignment. They are slightly offset so that when thecentral portion of the blank is raised relative to the outer edgesthereof to shape the blank into pyramidal form, the edges I9 and 20 ofthe split wall section will come together and the opposed score or foldlines brought substantially into coplanar alignment.

A tab 2| is formed integral with the wall section between the wallsections l3 and M which is disposed opposite to the split wall section,and said tab 2| is integrally connected to the outer edge of said wallsection from which it extends. A creased, scored or otherwise weakenedline 22 is provided at the junction of the tab 2| with the wall sectionfrom which it extends.

The blank being prepared as described in Fig. 1, the tab 2| is nextrebent against the under side of the blank and its exposed surface isthen coated or striped with adhesive material as indicated at 23. Theblank is next folded upon itself along some of the fold lines, in thisinstance the lines I2 and I5, so that the split wall section 5 betweenthe score lines II and i6 overlies the adhesive coated tab. The adjacentmarginal portions of the split wall section thus become adhesivelyunited to the tab and thereby connected to each other in fixedrelationship. The tab, being integrally united to one of the folds ofthe blank, .is thus also adhesively connected to the other fold andserves to maintain the blank in its folded compact condition. In thisform the device is in a convenient form for storage, wrapping, packingand shipping purposes.

The device when formed of an approximately hexagonal blank as described,may be set up into hexagonal, pyramidal form substantially asillustrated in Figs. 5 and 6. This is accomplished by severing the tab2| along its weakened fold line connection 22 from the fold of thedevice with which it is integral, thereby permitting the device to beunfolded. Inasmuch as the split wall sections are securely attached toeach other'in fixed relation, the device can no longer be flattened butwill retain the pyramidal form illustrated in Figs. 5 and 6.

One practical form of the device measures approximately 15 inches acrossand the height of the central portion is approximately 1% inches. Theseproportions are, of course, only by way of one example and are notessential. The size and shape of the device may be varied considerablyto meet various requirements. The device may be made larger or smallerthan the stated dimensions, and it may obviously be made in forms otherthan hexagonal.

Accordingly changes may be made in the described construction withoutdeparting from the spirit of the invention, the scope of which should bedetermined by reference to the following claims, the same beingconstrued as broadly as possible consistent with the state of the art.

I claim:

1. A golf practice hole comprising a sheet material member folded uponitself and having a tab integral with and extending from an edge portionof one of the folds, said tab being folded so as to be interposedbetween the folds of the member, and means uniting said tab to the otherfold, said tab serving to maintain the member in folded condition andbeing adapted to be severed from the fold from which it extends topermit unfolding of the member.

2. A golf practice hole comprising a sheet material member folded uponitself and having a tab integral with and extending from an edge portionof one of the folds, said tab being folded so as to be interposedbetween the folds of the member, the other fold comprising a pair of.sections having their adjacent edges located intermediate the width ofsaid tab when the member is folded, said tab thereby serving to holdsaid sections in predetermined, connected relationship and the member infolded condition, said tab being adapted to be severed from the foldfrom which it extends to permit unfolding of the member.

3. A device of the class described comprising a sheet material memberscored to form Wall portions so as to facilitate bending of the memberinto pyramidal form, one of the wall portions being split to permit themember to be initially formed in a fiat blank, a tab integral with andextending from the wall portion disposed opposite to said split wallportion, said tab being rebent to overlie the wall portion from which itextends, said member being folded so as to cause adjacent marginalportions of said split wall portion to overlie said tab, means unitingsaid tab to said overlying marginal wall portions whereby the latter aresecured to each other and the blank held in folded condition, said tabbeing adapted to be severed from the wall portion from which it extendsto thereby permit unfolding of the blank to said pyramidal form.

4. A device of the class described comprising a sheet material member ofapproximately hexagonal shape, said member being scored to form wallportions so as to facilitate bending of the member into hexagonal,pyramidal form, one of the wall portions being split to permit thememher to be initially formed in a flat blank, a tab integral with andextending from the wall portion disposed opposite to said split wallportion, said tab being rebent to overlie the wall portion from which itextends, said member being folded along some of the scoring so as tocause adjacent marginal portions of said split wall section to overliesaid tab, means uniting said tab to said overlying marginal wallportions whereby the latter are secured to each other and the blank heldin folded condition, said tab being adapted to be severed from the wallportion from which it extends to thereby permit unfolding of the blankto said hexagonal, pyramidal form.

5. A device of the class described comprising a sheet material memberscored to form wall portions so as to facilitate bending of. the memberinto pyramidal form, one of the wall portions being split to permit themember to be initially formed in a flat blank, a tab integral with andextending from the outer edge of the wall portion disposed opposite tosaid split wall portion, said tab being rebent to overlie the wallportion from which it extends, said member being folded so as to causeadjacent marginal portions of said split wall portion to overlie saidtab, means uniting said tab to said overlying marginal wall portionswhereby the latter are secured to each other and the blank held infolded condition, said tab being adapted to be severed along its foldline connection with the wall portion from which it extends to therebypermit unfolding of the blank to said pyramidal form.

6. A device of. the class described comprising a sheet material memberhaving a central hole and scored to form wall portions so as tofacilitate bending of the member into pyramidal form, one of the wallportions being split to permit the member to be initially formed in afiat blank, a tab integral with and extending from the outer edge of thewall portion disposed opposite to said split wall portion, said tabbeing rebent to overlie the wall portion from which it extends, saidmember being folded so as to cause adjacent marginal portions of saidsplit wall sections to overlie said tab, means uniting said tab to saidoverlying marginal wall portions whereby the latter are secured to eachother and the blank held in folded condition, the line of fold of. saidtab relative to the wall portion from which it extends being weakened tofacilitate separation of the tab from such wall portion to therebypermit unfolding of the blank and bending thereof to said pyramidalform.
